Do I have to be on Twitter?
Twitter is a short message communication tool that allows you to send out messages (tweets) up to 140 characters long to people who subscribe to you (followers).
Your tweets can include a link to any web content (blog post, website page, PDF document, etc.) or a photograph or video. People follow your Twitter account, and you follow other people. This allows you to read, reply to and easily share their tweets with your followers (retweet). It’s a good tool to market, connect with customers, peers, media and receive news. Most businesses are in Twitter.
